產品總覽

The LM43603PWPT is a SIMPLE SWITCHER® Synchronous Step-down Voltage Converter capable of driving up to 3A of load current from an input voltage ranging from 3.5 to 36V. The LM43603 provides exceptional efficiency, output accuracy and dropout voltage in a very small solution size. Peak current mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, extendable soft-start and tracking provide a flexible and easy to use platform for a wide range of applications. Discontinuous conduction and automatic frequency modulation at light loads improve light load efficiency. The family requires few external components and pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VCC under-voltage lockout, cycle-by-cycle current limit and output short circuit protection.
  • 27µA Quiescent current in regulation
  • High efficiency at light load
  • Meets EN55022/CISPR 22 EMI standards
  • Integrated synchronous rectification
  • Frequency synchronization to external clock
  • Internal compensation
  • Stable with almost any combination of ceramic, polymer, tantalum and aluminium capacitors
  • Power-good flag
  • Soft-start into pre-biased load
  • Extendable soft-start time by external capacitor
  • Output voltage tracking capability
  • Precision enable to program system UVLO
  • Output short-circuit protection with hiccup mode
  • Over-temperature thermal shutdown protection
  • Green product and no Sb/Br
